spraying devices. The widened or forkedend tilting of, the can under the sudden impact of of the said lever'is efficacious in preventing the I the ejector and in giving it vdirection into the chute. The-proper movement of the ejector for this purpose is given by the link connec- {.lJlOIl, 9. and cam-lever 10, operated by acam --1'1'-0n camshaft-6. The scape and e'ector l -levers above described are connecte with .cam-levers41and 10, respectively, which said levers are parallel and'pivo'ted both to -tlie-' cross-frame A f Figs. 4 and .5. The cams 9,5 one direction only;t'heir return movement bewhich operate them move-them positively in ing effected by'theirfown gravity and the gra'vity of the attachedweights 12=and 1 3. ;This

@nstr'uiztidnyhowevenis capable-ofmaterial alteration, as it is obvious that ether' varietiess of eccentric operating means ObVlitlilIl'g the roo weights, and even the links or cam-levers,'can 1 be employed with equal effect; The subjecting of the can to thefaction of the spraying device may also be aecomplished in different manners within the scope of this invention, it being bornein mindthat' the said device'm'ust momentarily jpreject within the can andsubse quently become removed relatively therefrom. As shown hereinythe spraying device S is stationary in respect of sue relative movement, andthe can is transferred into operative relation to it by means of a shdeway and a cooperating pusher-shaft. The slideway is composed of two parallel rods 14 14, suitably sup orted on'the frame transverse to the fee -chute and in such -position as to receive and support the can disc arged therefrom. The pusher-shaft 15 is m inted for longitudinal movement arallel with the slideway in a long journalearing 16, which also at fords-a convenient support for the ends of rods 14. 'At its inner end it is provided with an enlargement or head, which is'adapted to encounter the 1 can-bottom centrally, and its outer end is provided with an annularlygrooved collar 17, engaged by the forked end of a cam-lever 18. The latter is a'ppropri ately pivoted to the frame and is positively actuated in an outward direction by the cylinder-cam 19, return or inward movement 'being effected by a yielding force, such as a by link 19 to'slide thereon positively with.

the pusher-shaft. The distance between the pusher-head and said yoke is greater thanthe length of the can, so-that the latter may fall freely between the two upon the support or V slid eway.

pressure 26, Fig.

The specific constructionof the spraying device S forms no part ofthe present invention', and it will be sufficient to state briefly that it is comprised of a casing 22, bolted to the frame and also so formed as toprovide a seat for the ends of the rods 14, which constitute the can-supporting means'. A pipe 23 leads into this casing from a tank 24 of the hquidlimng material, and another pipe 25- leads into the chamber from a source of fluid- 7 and both pipes emerge rom the casing in the form of acompact shaft 27., terminated by a spray-head 28,'which is shown in enlarged scale in Figs- 7 and 8. This device comprises liq uid-tubes and fluidpressure tubes in atomizing-relation and so disposed as to emit a blast or spray when in operation throughout an arc of about one hundred and eighty degrees and in a substantially fixed plane, this being the most practical and eflicient-way of manipulating the extremely volatile and somewhat sticky material which forms the lining. For this reason it becomes necessary to rotate the can relatively to the said blast or spray, and while tion it is conveniently done )y rotating the pusher-shaft, for which purpose the gear or pulley 15 is splined to the said shaft and is driven by belt 29 or other equivalent gearing from the shaft 30, which latter is provided with a pinion 31, meshing with a spur-gear 32 on power-shaft- 33. In the above-dcscribed manner the pusher shaft is constantly rotated and at comparatively high speed. The spraying device S is provided with a rotary abutment S in the form ot'a flanged sleeve. supported on a tubular boss 22, surrounding the shaft 27. During that part of the operation in which a can is pressed against'this abutment S it is obvious that it and the can will be easily rotated by sha't't 15. The abutment is preferably faced with soft material, as leather or rubber, to all'ord a fricti m-bearing for the can-head; but this is not essential, and indeed the function of this abutment can be carried out by any fixed.antifriction means which will allow the can to be rotated by the said pushcr-shait.

For certain reasons it is desirable that the liquid lining material be kept in constant agitation, and for this purpose the supply-cock in the pipe 23 adjusted to deliver more of such liquid than is actually needed and the spraying device is provided with a pipe 34. which carries oil the excess, and the liquid in this pipe is iorced back into the tank 24 by a pump 35. The latter is constantly driven by the eccentric-rod 3.6 and eccentric 36 on the power-shaft 33, in this manner keeping up a continuous circulation of the said liquid through the spraying device. The forcepipe 34 of the pump debouches near the bottom of the tank and is preferably tapered so that the discharge therefromwill tend to produce a commotion of the liquid. Other and additional means may also be supplied, if desired, to keepnp an agitation of the lit uidv contained in tank 24. The air or other uid pressure involved with the spraying device is automatically controlled by the apparatus to come into action int'rx ittently, or at such times as the cans surrouriilt Such pressure-controlling means, is most 0011-. veniently a stop cook or valve 37, applied to pipe 25 and operated by a link 38 and camlever 39, in turn actuated by a cam 39 on the shaft 6; but the plunger of an air-compressor might obviously be 0 erated by said camshaft to produce the esired air-blast in the spray-head.

The shaft 6 is common to the various mechanisms of the machine, bein driven from the power-shaft 30 by means 0 a pinion 40 and spur-gear 41. The cam 39 on the gear 41 is adjustable thereon so as to vary the time as well as the force and duration of the action of the spraying device. The other cams on he spray-head 28.'
